.ings, forming part of this specification, in

Figure 1 is a vertical section partly broken away of a barometriccondenser embodying my invention; and Fl," 2 is a similar view of aportion of the condenser showing :1 modified construction My inventionhas relation to the class of barometric condensers, and is designed toprovide a novel arrangement of the steam pipe which carries the steam tobe condensed into the condenser.

Heretofore it has been the practice to bring the steam. pipe into thecondensing chamber through the side wall of thesame: This practice hasnecessitated the use of at least two large elbows in the steam pipe I?sulting in increased friction on the steam and also increasing theexpense of construction, these steam pipes being often of largediameters.

According to my invention, I extend the steam pipe vertically into thecondensing chamber, its upper end terminating within said chamberpreferably at a point below the water inlet and provided with means ofsuitable character for preventing dis charge of the water into thepipe.This not only effects a saving of at least one elbow in the steam ipe,but it also enables the steam pipe to e used as a support for thecondenser when desired The precise nature of my invention will be bestunderstood by reference to the accompanying drawings, in which. I haveshown twodiifcrent embodiments thereof, it being premised, however, thatvarious other modifications may be made therein by those skilled in theart without departing from the spirit and scope of my invention asdefined by the ap ended claims.

Referrin first to tie construction shown in Fig. 1, tie numeral 2designates the condensing chamber having an inlet opening at 3 forconnection with the usual water-sh ply pipe and an opening 4 at itsupper on for the exhaust or vacuum pipe. 5 and 6 designate interiorcones and caps, or

battles. arranged to produce a spraying action of the water dischargedinto the chamber at the opening 3. Any suitable ployed. In thearrangement as shown the water entering at the opening 3 flows over theupper end of the upper conch; thence downwardly into the cup below thetop opening in said cone and over the edges of the cup into the lowercup 6 over the edges of which it is discharged. 7 designates the steaminlet pipe, which forms a vertical cohunn. upon which the condenser issupported, and which extends upwardly into the lower portion of thecondensing chamber, terminating in a slotted or erforatcd head 8 throughwhich the steam is discharged, this head being closed at its upperarrangement of these battles may be emend to prevent the directdischarge of.water liicrcin. 9 designates the tail pipe connected withthe lower portion of the chamber 2, and which discharges into the well10 at its lower end in the usual manner, or which may be provided withthe free steam exhaust arrm'igcment described and claimed in my PatentNo. 887,63 dated May 12, 1908. One or more of these tail pipes may beemployed, as may be desired.

In the modification shown in Fig. 2, the head 11 of the steam pipe is ofsomewhat difl'ei'ont form, being referably a part of the casting 12which orms the lower section of the inclosing'wall of the condensingchamber It will be seen that the steam will be discharged from theopenings in the 11 per ends of the steam inlet pipes into the fa waterdischarged from the cups or baflles, so that a cmnpletc condensation ofthe steam will take place.

It will be obvious that the form of the discharge head of the steam pipemay be changed in various ways; and that an suitable arrangement ofmeans for re racing the water spray may be employe 1 claim 1. Abarometric condenser having a suction pipe connected with the upperportion of its condensing chamber, a steam inlet pipe extendinvertically upward through the bottom we 1 of the condenser andterminating within said chamber, and means for discharging water intosaid chamber intermediate o the upper end of the steam pipe and of the'point of connection of the suction pipe, the suction pipe acting tocreate a counter current of steam upwardly through the discharged water;substantially as described.

2. A barometric condenser having a suction pipe connected with the upperportion of its condensing chamber, a steam inlet pipe extendingvertically u wardly through the bottom wall of the cbn enser andterminating within said chamber, means for dis chargm water into saidchamber intermediate o the upper end of the steam pipe and of the pointof connection of the suction pipe, the suction pipe acting to create aof steam upwardly through of the condensing chamber to one side of thesteam pipe and adapted to contain a barometric column of water;substantially as described.

3. i barometric condenser having a suction pipe connected'with the upperportion of its condensing chamber, a steam inlet pipe extendingvertically upward through the bottom wall of the condenser andterminating within said chamber, means for discharging water into saidchamber intermediate of the upper end of the steam pipe and of the pointof connection of the suction pipe, the suction pipe acting to create acounter-current of steam upwardly through the discharged water, and saidpipe having means at its upper end for preventing the discharge of waterthereinto; substantially as described.

4. A barometric condenser having a steam inlet pipe extending verticallyupwards into the condensing chamber and terminatin with a laterallyperforated or slotted hea and a tail pipe connected to the lower portionof the condensing chamber to one side of the steam pipe; substantiallyas described.

In testimony whereof, I have hereunto set my hand.
